The electrical scheme of the model aeroplane.
We will recapture the topic of the broadcasting station when we need to form it, now we are going to continue with the scheme of the wiring of the model aeroplane.
In the plane there are going to go the battery, the variador (ESC), the engine, the recipient and the servos. Observe in the attached scheme how everything is organized.
>
The heart of the team is the ESC. The brain, the recipient. The battery gives the energy to the ESC and this one is in charge of feeding to the engine, and also of giving the current for the recipient and the servos.
ATTENTION when we are going to buy it, since it must incorporate that, the aptitude to give from 4 to 6 volts to feed the servos and the recipient.
This characteristic is defined as BEC. (battery eliminator circuit). Namely circuit for elimination of the additional battery that must feed the servos and the recipient. (searched, eh).
ESC 30 To with BEC.
That of the photo, it incorporates it, and according to the manufacturer he has 1 for to feed the recipient and the servos.
The servos have 3 cables, positive, negative (mass) and sign. Between positive and negative comes to them the electrical feeding and between sign and negative (Mass) the instructions come to them on the position that they must have.
Of the ESC also three cables go out. But in this case the positive gives the feeding. Then the recipient acts like a space of share-out of the feeding, as indicates the stated scheme at first.
Recipient, attention to the pin in that it is possible to plug the other way round and it would provoke serious breakdown.
In case we buy an ESC without BEC (thing that I do not recommend), we do not have any more remedy that to mount an independent BEC, for receiving it has the position free in the space of above, and BAT sets.
ESC of 40 To with BEC of 4 To.
There is ESC of major capacity as that of the photo, which there puts SBEC (Super BEC) that gives a little more of current, 4 amperes.
From the electronic point of view the device is "flipante". Try to make with classic components a regulator that takes any tension between 3 and 24 V. and leaves it between 4 and 6 V, practically without losses, since almost there is no spendthrift, also, with aptitude to feed engines (Servos). All this, also logically, of being able to control up to 40 amperes with control of temperature, of phase and control of batteries, configurable and a heap of functions more.... and for these prices..... and with the size of a pair of euros.... flipante.....
Defining a model aeroplane.
We are going to speak on the general concepts, to be defining the necessary material. In successive articles the elements will talk each other with more details.
What do we claim to make to fly?
To acquire a set we must have an idea of what is going to weigh our experimental plane. Since always, the most economic thing is the standard thing, therefore, we go to go to the stripe of 500-800 grams.
Departing from this, we are going to choose the engine. We have already said that it is going to be brushless (without brushes, it takes three cables), also it is going to be outrunner, therefore, we go away to the shop that more we like, and choose an engine that has a potency of between 150 and 200 W. We can find them from 4 euros, like that of the photo.
Adapted to this we must choose the ESC. In the card of the engine there says which is going to be the maximum current that is going to spend and usually indicates the current (Amperes) of the recommended ESC. This debit to be always of current superior to the respondent for the engine (I choose one of 30 To, that of the photo, instead of 20th, for 1 euros more).
I have not proved other of another mark, but attentive that there exist other marks that they need an additional programmer to form it. This mark is formed by tones, is slow but simple.
It will continue ….
